Tuber the size of a chestnut. Leaves 6-10 by 2-2} in., subsessile or petioled. 
Scape with raceme 1-2 ft. ; sheaths long, loose ; flowers 14 in. long, narrow, purple ; 
pedicels short; bracts linear.—I find no evidence of Blume's ** Centuria ” ever having 
been published, or even printed ; if it was so, his name has priority. 
42. GEODORUM, Jackson. 
Terrestrial herbs, rootstock tuberous hypogeal. Leaves elliptic, acute, 
plicate. Scape from the rootstock, stout, erect, sheathed, shorter than the 
leaves; flowers crowded in decurved racemes, bracts narrow membranous. 
Sepals and broader petals conniving or spreading. Lip sessile on the base 
or short foot of the column, cymbiform, membranous, margins involute, 
disk with or without ridges ending in calli, and with a forked baal 
callus. Column short, stout; anthers 2, cells, appendaged after dehiscence 
by the persistent detached faces of the cells; pollinia 2, broad foveolate 
sessile or subsessile on a broad strap or gland.—Species 6-8? Indian, 
Malayan and Australian. 
I am unable to define the species from Herbarium specimens, or to reduce to any 
system the descriptions and drawings of Roxburgh, Brown, Lindley and Griffith. 
The following descriptions are provisional only. I have spent days to no purpose in 
endeavours to improve on it by the analysis of specimens.

Brown's G. purpureum was founded on Roxburgh’s drawing of Limodorum nutans, 
a native of the Circars, but of which no specimen is recorded to exist, It is repre- 
sented and described as having the scape longer than the leaves, a lax-fld. raceme, 
and an acute lip; characters not hitherto found in any Geodorum. But if it be 
allowed that the elongate scape and lax-flowered raceme are due to the lengthening
